Operation

Encrypt

Decrypt

Algorithm (for Encryption)

AES-GCM (Recommended)

AES-CBC

AES-GCM provides authenticated encryption.
AES-CBC is also common but lacks built-in authentication.

Message to Encrypt

0 / 2000 characters

Password

Used to derive the encryption key. Remember this password!

Secure Browser Encryption

Uses Web Crypto API (AES-GCM / AES-CBC) for strong, browser-based encryption. All encryption and decryption happens locally in your browser - no data is sent to any server.

Security Note: Ensure you use a strong password and store it securely. We don't store your data or password.
